In the past, bunk beds used twin mattresses on the top and bottom bunks, which gave anyone larger than a small child very little room to move around.

Types of Bunk Beds to Consider

How to Choose the Right Size for Bunk Bed MattressBunk beds have two beds in one, with one bed positioned a few feet over the other one. These give you room for more than one person to sleep without requiring the space for two separate beds. There are several size options available, which we’ll discuss below.

Double twin

The double twin bunk bed includes a twin mattress on the top and bottom bunks. These are the standard bunk bed mattress size, with dimensions of 38 x 75 inches for each bunk, and the most common one used. You can use any twin mattress for these beds.

DIY

If you are on a crafty side, you can always create your own bunk bed, but always use standard size measurements so you could get mattress to fit:

Double full

A double full bunk bed uses these larger mattresses on the top and bottom bunks. Though they take up more room due to the bigger bed sizes, they are more comfortable for teenagers or adults to sleep on. These beds require mattresses sized at about 53 x 75 inches, so you do need more space in the room you’re using them in, though they still take up less room than two separate beds.

Double twin XL

Double twin XL bunk beds aren’t as common as the regular twin models, though they are a must for taller individuals. Though they have the same width as a twin mattress, they are 80 inches long, making them about the same length as a queen or king mattress. You can even get a twin XL mattress topper to add a bit more cushion if needed.

Twin and full combo

The twin and full combo bunk bed has become one of the more common mattress combinations, with a twin bed on top and a full mattress on the bottom. This is best for kids of varying ages or when you need room for three to sleep but don’t have room for extra beds.

Shorty

How to Choose the Right Size for Bunk Bed MattressShorty bunk beds are just like regular bunk beds with one very important exception. These are much shorter at about 50 to 55 inches in height, reducing the risk of serious injury if a child should happen to fall out of the top bunk at some point. This makes them a great option for smaller children, plus they fit much better in rooms with low ceilings than a regular-sized bunk bed.

Trundle

You can slide this mattress out whenever needed and then slip it back beneath that lower bunk when you’re finished with it. For those with limited space but still need room for a third person, the trundle bunk bed is a great option.

Futon

How to Choose the Right Size for Bunk Bed MattressA futon bunk bed has a regular bunk on top with a futon on the bottom. These are great for small apartments or dorm rooms with limited space for furniture since the futon can be used as a couch during the day and a bed at night. Futon mattresses are thinner than standard options, so you do need a special one to fit this area.

Bottom Queen/King combo

Bunk beds with a Queen or King mattress on the bottom and a twin or twin XL on top are rare but not impossible to find. These are great for adults who need to share a sleeping area with their kids, though you do need a large master bedroom to house this piece of furniture.

What Makes Bunk Bed Mattress Stand Out

When choosing a new mattress, there are a few features that you may want to keep an eye out for to ensure you’re getting a quality model.

Quiet

When you sleep on a bunk bed, any noise from the other bunk can keep you awake. Reducing the amount of noise by using quiet mattresses that contain foam instead of springs can help reduce the creaks when sleepers move around in bed at night.

How to Choose the Right Size for Bunk Bed Mattress

Low profile

Bunk beds include safety rails but the shorter rails are useless if the mattress is higher than the top of the rail. A low-profile mattress is about 6 to 7 inches high, which keeps it below these types of guard rails while still offering plenty of comfort.

Temperature control

Heat rises, making the top bunk warmer at all times, which can be especially uncomfortable during the summer months. Luckily, many mattresses include cooling technology that helps reduce the heat for a more comfortable sleep.

Weight

Though the weight of a bottom bunk mattress may not matter, a heavy one on top could damage the support beneath it and become a safety hazard to both sleepers. The lighter the mattress, the safer it is on that top bunk.
